Description

Technical Field

[0001] This application relates to the field of surveillance equipment technology, and in particular to a camera structure. Background Technology

[0002] Speakers are typically installed on cameras to serve as warnings when necessary. To facilitate the propagation of sound from the speaker, a sound outlet is required on the camera housing that connects to the sound cavity.

[0003] However, current sound outlets have a limited ability to block water. Since cameras are mostly used in outdoor scenes, they often face problems such as rain and snow, which makes it easy for moisture from the external environment to seep into the housing through the sound outlet, affecting the sound output of the speaker. Utility Model Content

[0004] Therefore, it is necessary to provide a camera structure that can improve the waterproof capability at the sound outlet, enhance the protection of the speaker, and extend the speaker's service life.

[0005] A camera structure includes a housing and a speaker assembly mounted on the housing. The housing has a plurality of spaced-apart sound-emitting protrusions on a side away from the speaker assembly. Each sound-emitting protrusion includes a retaining side portion connected to the housing and a protruding end portion connected to an end portion of the retaining side portion away from the housing. At least a portion of the retaining side portion of the sound-emitting protrusion has a sound-emitting hole and / or the connection between the retaining side portion and the housing has a sound-emitting hole.

[0006] Understandably, the protruding ends of the sound outlet bumps serve to prevent water from directly entering the enclosure and the connection between the enclosure and the housing. Therefore, placing sound outlet holes on the enclosure side or at the connection between the enclosure and the housing reduces the risk of water entering the sound outlet directly and minimizes the amount of water seeping in through the sound outlet. Furthermore, by using multiple sound outlet bumps, the size of a single sound outlet can be reduced while maintaining a wide sound output range, further reducing the risk of water seepage through the sound outlet. This improves the waterproofing of the sound outlet area on the housing, enhances the protection of the speaker components, and facilitates long-term use.

[0007] In some embodiments, the side and / or bottom regions of the sound-emitting protrusion are provided with the sound-emitting hole.

[0008] Understandably, utilizing the sound outlets in the side and bottom areas ensures a sufficient sound output range while reducing the amount of water seeping in from above the sound outlet protrusions, thus further improving waterproof performance.

[0009] In some embodiments, the sound outlet is provided with a plurality of circumferentially spaced holes arranged along the corresponding sound outlet protrusions.

[0010] This design ensures a wide sound output range while maintaining the connection strength of the sound output protrusion itself, and also facilitates manufacturing.

[0011] In some embodiments, among the plurality of sound-emitting protrusions in the same column and / or among the plurality of sound-emitting protrusions in the same row, a reinforcing portion is provided between any two adjacent sound-emitting protrusions.

[0012] Understandably, the reinforcement section enhances the connection strength between any two adjacent sound outlet protrusions, preventing deformation or damage to the sound outlet protrusions due to uneven stress during use, thereby improving the protection of the sound outlet.

[0013] In some embodiments, the reinforcing portion divides the sound-emitting protrusion into a left region and a right region, wherein the left region and / or the right region are provided with the sound-emitting hole.

[0014] This design is equivalent to having sound outlet holes on both sides of the reinforcing part where the sound outlet protrusion is located, which increases the sound outlet range while reducing water seepage.

[0015] In some embodiments, among the plurality of sound-emitting protrusions in the same column, the reinforcing portion is connected to the opposite side of both the first and last sound-emitting protrusions.

[0016] This design further enhances the connection strength between multiple sound-emitting protrusions in the same column and the housing, fully ensuring the effectiveness of each sound-emitting hole, reducing the risk of sound hole deformation due to deformation of the sound-emitting protrusions, and guaranteeing sound quality.

[0017] In some embodiments, a portion of the housing protrudes from the inside out to form the reinforcement and / or the sound-emitting protrusion; and / or, a sound cavity is provided between the inner wall of the housing and the speaker assembly, and each of the sound-emitting protrusions is surrounded by a cavity through the corresponding enclosure side and the protruding end, the cavity communicating with the sound cavity and the sound outlet.

[0018] This design not only facilitates manufacturing and reduces costs, but also simplifies the process of opening holes on the upper side of the sound-emitting protrusion. It only requires penetrating along the thickness direction of the side of the enclosure to achieve the purpose of sound emission.

[0019] In some embodiments, a waterproof and breathable membrane is provided between the inner wall of the housing and the speaker assembly to further enhance the protection of the speaker assembly.

[0020] In some embodiments, a plurality of the sound-emitting protrusions collectively define a sound-emitting portion located on the housing, and the edge of the waterproof and breathable membrane is provided with an annular protrusion, which surrounds the outer periphery of the sound-emitting portion.

[0021] Understandably, the annular protrusions can be used to bond and fix the membrane to the casing, and a certain gap can be left between the central area of ​​the waterproof and breathable membrane and the central part of the casing at the sound outlet, so as to reduce the impact of external water flow on the waterproof and breathable membrane.

[0022] In some embodiments, the housing is recessed with a receiving groove, and a plurality of sound-emitting protrusions protrude from the bottom of the receiving groove toward a side away from the housing and are arranged at intervals.

[0023] Understandably, the design of the receiving groove can shield the sound outlet, reducing the risk of rainwater directly impacting it; moreover, this design protects the sound outlet protrusion, reducing the risk of it being hit. Attached Figure Description

The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0036] Please see Figures 1 to 4One embodiment of this application provides a camera structure that can improve the waterproof capability of the sound outlet 1101, reduce the amount of water seeping in from the sound outlet 1101, thereby improving the protection of the speaker and extending the service life of the speaker. Specifically, the camera structure includes a housing 10 and a speaker assembly 20 mounted on the housing 10. The housing 10 has a plurality of spaced sound outlet protrusions 11 on the side away from the speaker assembly 20. The sound outlet protrusions 11 include a retaining side 111 connected to the housing 10 and a protruding end 112 connected to the retaining side 111 away from one end of the housing 10. At least some of the retaining side 111 of the sound outlet protrusions 11 have sound outlet holes 1101 and / or the connection between the retaining side 111 and the housing 10 has a sound outlet hole 1101.

[0037] Taking the X-axis direction as an example, and for ease of description, the area defined by multiple sound-emitting protrusions 11 is called the sound-emitting part 102.

[0038] When testing the waterproof performance of the speaker outlet 102 of the housing 10, water is usually sprayed onto the front of the housing 10. If there is a speaker outlet on the front of the housing 10, water can easily seep into the interior of the housing 10 through the outlet, affecting the speaker assembly 20 or even damaging it.

[0039] Based on this, the camera structure provided in this embodiment has a sound outlet 1101 provided on the enclosure side 111 of the sound outlet protrusion 11 or at the connection between the enclosure side 111 and the housing 10, or both the enclosure side 111 and the connection between the enclosure side 111 and the housing 10 have a sound outlet 1101. This arrangement is equivalent to setting the sound outlet 1101 relative to the side of the housing 10, i.e., side sound outlet. Compared to front sound outlet, the protruding end 112 on the sound outlet protrusion 11 can form a barrier on the enclosure side 111 and the area at the connection between the enclosure side 111 and the housing 10. The protruding end 112 can face the water directly, thus preventing water from flowing towards the sound outlet 1101, thereby reducing the risk of the sound outlet surface facing water directly and reducing the amount of water seeping in through the sound outlet 1101. Furthermore, by utilizing the multiple sound-emitting protrusions 11, the size of a single sound-emitting hole 1101 can be reduced while maintaining a large sound emission range, further reducing the risk of water seepage through the sound-emitting hole 1101. This significantly improves the waterproof capability of the housing 10 at the sound-emitting section 102 and even at each sound-emitting hole 1101, enhancing the protection of the speaker assembly 20 and facilitating long-term use.

[0040] This can be achieved by providing a sound outlet hole 1101 for each sound-emitting protrusion 11, or by providing a sound outlet hole 1101 for only a portion of the sound-emitting protrusions 11. Alternatively, some sound-emitting protrusions 11 may have a sound outlet hole 1101 on the side enclosure 111, while other sound-emitting protrusions 11 may have a sound outlet hole 1101 at the connection between the side enclosure 111 and the housing 10. It is even possible for each sound-emitting protrusion 11 to have a sound outlet hole 1101 at the connection between the side enclosure 111 and the housing 10. The key is to achieve both sound output and waterproofing; this is merely an example.

[0041] In some embodiments, the sound-emitting protrusion 11 has corresponding sound outlet holes 1101 on both its side and bottom regions. That is, a sound outlet hole 1101 is not required on the bottom region of the sound-emitting protrusion 11. This arrangement takes into account that in actual use, when rainwater falls from above onto the housing 10, it may seep into the housing 10 from the top of the sound-emitting protrusion 11. Therefore, by utilizing the sound outlet holes 1101 in the side and bottom regions, sufficient sound output range is ensured on the one hand, and the amount of water seeping in from above the sound-emitting protrusion 11 is reduced on the other hand, further improving waterproof performance.

[0042] like Figure 2 As shown, the areas on opposite sides of the sound-emitting protrusion 11 along the Y-axis are designated as side areas, and the area below along the Z-axis is designated as the bottom area. Therefore, sound holes 1101 can be provided on opposite sides of the side portion 111 along the Y-axis, and a sound hole 1101 can be provided below the side portion 111 along the Z-axis. These sound holes 1101 are arranged at circumferential intervals along the sound-emitting protrusion 11 to ensure that each sound hole 1101 is relatively small.

[0043] In other words, the number of sound outlet holes 1101 on the sound outlet protrusion 11 can be multiple, and they are arranged at intervals along the circumference of the corresponding sound outlet protrusion 11. This arrangement can ensure a wide sound outlet range while maintaining the connection strength of the sound outlet protrusion 11 itself, and is also convenient for manufacturing. Specifically, when both the side enclosure 111 and the connection between the side enclosure 111 and the housing 10 are provided with sound outlet holes 1101, these two sound outlet holes 1101 are arranged at intervals along the X-axis direction.

[0044] Alternatively, the sound outlet 1101 may be provided only in the side area, for example, at least one side of the enclosure side 111 along the Y-axis direction may have a sound outlet 1101. The sound outlet 1101 in the side area is more suitable for the downward flow of water under its own gravity, thereby reducing the amount of water seeping in through the sound outlet 1101. Of course, the sound outlet 1101 may also be provided only in the bottom area.

[0045] Please see Figures 1 to 4In some embodiments, among the multiple sound-emitting protrusions 11 in the same column, a reinforcing portion 12 is provided between any two adjacent sound-emitting protrusions 11. It can be understood that the provision of the reinforcing portion 12 enhances the connection strength between any two adjacent sound-emitting protrusions 11, preventing the sound-emitting protrusions 11 from deforming or being damaged due to uneven force during use, thereby improving the protection of the sound outlet 1101 and ensuring the stability and clarity of the sound quality output.

[0046] Alternatively, among the multiple sound-emitting protrusions 11 in the same row, a reinforcing portion 12 may be provided between any two adjacent sound-emitting protrusions 11. Alternatively, among the multiple sound-emitting protrusions 11 in the same row and among the multiple sound-emitting protrusions 11 in the same column, a reinforcing portion 12 may be provided between any two adjacent sound-emitting protrusions 11. Furthermore, if the cross-section of the aforementioned sound-emitting portion 102 is square or near-square, a reinforcing portion 12 may be provided between any two adjacent sound-emitting protrusions 11 in a group of sound-emitting protrusions 11 parallel to the diagonal. The only requirement is to improve the structural strength of each sound-emitting protrusion 11; this is merely an example.

[0047] Furthermore, taking the example of multiple sound-emitting protrusions 11 in the same column corresponding to reinforcing parts 12, the first and last sound-emitting protrusions 11 in the same column are both connected to the reinforcing parts 12 on opposite sides. This arrangement further enhances the connection strength between the multiple sound-emitting protrusions 11 in the same column and the housing 10, fully ensuring the effectiveness of each sound hole 1101, reducing the risk of deformation of the sound hole 1101 due to deformation of the sound-emitting protrusions 11, and ensuring sound quality.

[0048] Furthermore, each connection point is connected to the housing 10. This increases the structural strength of the housing 10 at the sound outlet 102, improves the stability of the housing 10 under sound wave impact, and thus ensures clear and pure sound quality.

[0049] like Figures 2 to 4 As shown, in some specific embodiments, a portion of the housing 10 protrudes from the inside out to form a reinforcing portion 12 and a sound-emitting protrusion 11. This design allows for the direct machining of the reinforcing portion 12 and the sound-emitting protrusion 11 into a portion of the housing 10 itself using a stamping process, facilitating manufacturing and reducing costs. Alternatively, machining can be used, or the connecting portion can be bonded to the outer wall of the housing 10 and fixed to the surrounding side 111 of the sound-emitting protrusion 11. Alternatively, multiple sound-emitting protrusions 11 and multiple connecting portions can be integrally formed and then bonded as a whole to the outer wall of the housing 10. In this case, the housing 10 has corresponding through holes to facilitate sound emission. This is merely an example.

[0050] The reinforcing part 12 can be strip-shaped, block-shaped, or other suitable shapes, and its material can be the same as or similar to the sound-emitting protrusion 11 to ensure overall harmony and stability. The reinforcing part 12 can be solid or hollow.

[0051] In some specific embodiments, the reinforcing part 12 is arranged in a strip shape. This arrangement allows the reinforcing part 12 to reduce the space occupied by the circumferential upward space of the sound-emitting protrusion 11 while connecting any two adjacent sound-emitting protrusions 11, thus ensuring a sufficient sound output range.

[0052] Furthermore, each sound-emitting protrusion 11 is surrounded by a cavity connecting the sound cavity 501 and the sound outlet 1101 through the corresponding enclosure side 111 and protruding end 112. This arrangement reduces the difficulty of opening the upper part of the sound-emitting protrusion 11, as it only needs to penetrate along the thickness direction of the enclosure side 111 to achieve the purpose of sound emission, which is simple and quick. Among them, the reinforcing part 12 is solid, which can be used to separate any two adjacent sound-emitting protrusions 11, ensuring independent sound emission of the sound outlet 1101 at any two adjacent sound-emitting protrusions 11, thus guaranteeing sound quality; moreover, this arrangement can significantly improve the structural strength.

[0053] Furthermore, the projection of the reinforcing part 12 along the X-axis can be rectangular or square, and the projection of the sound-emitting protrusion 11 along the X-axis is circular, with the diameter of the circle being larger than the width of the rectangle. The reinforcing part 12 is connected to the middle of the sound-emitting protrusion 11 to improve the uniformity of the distribution of the sound-emitting holes 1101 and ensure better sound output.

[0054] In some embodiments, the reinforcing portion 12 divides the sound-emitting protrusion 11 into a left region and a right region, both of which are provided with sound-emitting holes 1101. Taking a circular cross-section of the sound-emitting protrusion 11 as an example, the sound-emitting protrusion 11 protrudes from the reinforcing portion 12 on both sides along the Y-axis, which facilitates the setting of the sound-emitting holes 1101. This arrangement is equivalent to the sound-emitting protrusion 11 being provided with sound-emitting holes 1101 on both sides of the reinforcing portion 12 along the Y-axis, increasing the sound emission range. Each sound-emitting hole 1101 can be arranged in an arc shape that matches the circular shape of the sound-emitting protrusion 11.

[0055] Please see Figures 1 to 4In some specific embodiments, the housing 10 is recessed with a receiving groove 101, and a plurality of sound-emitting protrusions 11 are at least partially disposed within the receiving groove 101. That is, the enclosure side 111 of each sound-emitting protrusion 11 is connected to the bottom wall of the receiving groove 101, and a sound outlet 1101 penetrating to the sound cavity 501 is provided between the enclosure side 111 and the bottom wall of the groove. Moreover, the receiving groove 101 can shield the sound outlet 1101, reducing the risk of rainwater directly impacting the sound outlet 1101; and this arrangement also protects the sound-emitting protrusions 11, reducing the risk of the sound outlet protrusions 11 being impacted.

[0056] Specifically, the protruding end 112 of the sound-emitting protrusion 11 may not protrude beyond the opening of the receiving groove 101. For example, the protruding end 112 may be flush with the opening of the receiving groove 101, or the entire sound-emitting protrusion 11 may be located within the receiving groove 101. The aforementioned reinforcing portion 12 connecting any two adjacent sound-emitting protrusions 11 also does not protrude beyond the opening of the receiving groove 101, reducing the risk of collision and improving safety.

[0057] Furthermore, along the X-axis, the projection of the receiving groove 101 is greater than the projection of the sound output section 102, which is defined by multiple sound output protrusions 11 and multiple reinforcing parts 12. This arrangement leaves a certain space near the outer periphery of the receiving groove 101, which facilitates the installation of the speaker assembly 20 inside the housing 10.

[0058] Please see Figure 1 , Figure 3 , Figure 4 and Figure 5 In some embodiments, a waterproof and breathable membrane 30 is provided between the inner wall of the housing 10 and the speaker assembly 20 to further enhance the protection of the speaker assembly 20. The speaker assembly 20 includes a speaker body 21 and a mounting base 22. The mounting base 22 has a mounting cavity, in which the speaker body 21 can be snapped. The mounting base 22 also has a wiring hole 2201 for wiring of the speaker body 21, and a rubber plug 23 is provided at the wiring hole 2201 to ensure the sealing of the wiring hole 2201. The mounting base 22 can be fixed to the housing 10 with screws 42 to meet the assembly of the speaker assembly 20 relative to the housing 10. The housing 10 surrounds a mounting cavity 103, and a circuit board is provided in the mounting cavity 103. The wires 24 of the speaker body 21 are electrically connected to the circuit board for power supply and control.

[0059] Understandably, the side-mounted sound outlet 1101 on the sound outlet protrusion 11 reduces the risk of water flowing directly into the sound outlet 1101, thereby reducing the amount of water seeping in through the sound outlet 1101, improving the protective properties of the waterproof and breathable membrane 30, and preventing the risk of the waterproof and breathable membrane 30 easily falling off due to seepage.

[0060] Furthermore, the camera structure also includes a sealing ring 41, which is pressed between the mounting base 22 and the housing 10 to ensure the assembly sealing of the speaker body 21. A sound cavity 501 is formed between the speaker body 21 and the inner wall of the housing 10, and the aforementioned sound outlets 1101 communicate with the sound cavity 501.

[0061] In some embodiments, the edge of the waterproof and breathable membrane 30 is provided with an annular protrusion 31, which surrounds the outer periphery of the sound outlet portion 102. Specifically, part of the shell wall of the housing 10 can be stamped to protrude from the outside to the inside, forming the aforementioned receiving groove 101 on the outer wall of the housing 10, and forming an inwardly protruding part on the inner wall of the housing 10, with an annular mounting protrusion 13 protruding inward at the edge of the protruding part. The mounting base 22 in the speaker assembly 20 is pressed into the mounting protrusion 13 and fastened with screws 42. A sealing ring 41 is pressed into the pressing point of the mounting protrusion 13 and the mounting base 22 to ensure sealing. The mounting protrusion 13 ensures that a sound cavity 501 is formed between the speaker body 21 and the protrusion. The protrusion is provided with an outwardly recessed mounting groove 104, in which the aforementioned waterproof and breathable membrane 30 is installed. For example, the waterproof and breathable membrane 30 can be glued and fixed. Because of the annular protrusion 31 on the waterproof and breathable membrane 30, it can be bonded and fixed to the housing 10 by applying adhesive to the annular protrusion 31. It can also make a certain gap remain between the middle area of ​​the waterproof and breathable membrane 30 and the housing 10 in the middle of the sound outlet 102, further reducing the impact of external water flow on the waterproof and breathable membrane 30.

[0062] In this design, along the axial direction (i.e., the X-axis) of the sound-emitting protrusion 11, a portion of the projection of the annular protrusion 31 coincides with the projection of the sound-emitting portion 102. In other words, the inner edge of the projection of the annular protrusion 31 along the X-axis coincides with the edge of the projection of the sound-emitting portion 102 along the X-axis. This arrangement ensures that the waterproof and breathable membrane 30 can be securely installed on the housing 10, guaranteeing sufficient bonding area with the housing 10 while increasing the waterproof effect at the edge of the sound-emitting portion 102. Furthermore, this arrangement effectively increases the size of the annular protrusion 31, enhancing the overall strength of the waterproof and breathable membrane 30. This improves the stability of the waterproof and breathable membrane 30 during long-term use, ensuring it maintains good sealing and breathability in various environments, thereby extending the speaker's lifespan.

[0063] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
